Fresh protests against Israel are expected in the Palestinian territories, a day after Israeli troops killed 55 people in the Gaza Strip.
Tuesday marks the 70th anniversary of what Palestinians call the Nakba, or Catastrophe, that saw thousands flee amid the creation of Israel in 1948.
Tensions will be high in Gaza where those killed on Monday will be buried.
The violence came as the US completed the move of its embassy to Jerusalem from Tel Aviv, incensing Palestinians.
They claim East Jerusalem as the capital of a future Palestinian state and see the US move as backing Israeli control over the whole of the city - which Israel regards as its indivisible capital.
Palestinian officials said that, as well as those killed, about 2,700 people were injured in Monday's violence - which they condemned as a massacre. It was the deadliest day in Gaza since the 2014 war.
Israeli PM Benjamin Netanyahu said his military was acting in self-defence against Gaza's Islamist rulers, Hamas, who he said wanted to destroy Israel.
